Conducted as part of phase one of the US Army’s XM1155 Extended-Range Artillery Projectile (ERAP) program, the SFRJ tests validated gun-launched survivability and performance predictions, and demonstrated the potential of extending projectile range to more than 100 kilometres, which is a significant increase compared with current fielded artillery projectiles.
The XM1155 ERAP program will provide an extended range, guided 155mm artillery round capable of defeating moving and stationary targets in all terrain and weather conditions.
Pat Nolan, vice president of missile products at Northrop Grumman, said, “Successful completion of the rigorous tests of the Solid Fuel Ramjet demonstrates maturation of the technology to survive the very challenging gun-launch environment and significantly extend the range of the US military’s current field artillery with a high level of confidence.
Work under the contract will be completed at the Allegany Ballistics Laboratory in Rocket Center, West Virginia; Ronkonkoma, New York; Plymouth, Minnesota; and in partnership with SPARC Research based out of Warrenton, Virginia.
“The munition system is being designed to provide multi-domain battlespace dominance against high-level targets,” Nolan added.
Northrop Grumman solves the toughest problems in space, aeronautics, defence and cyber space to meet the ever-evolving needs of customers worldwide.
The company’s 90,000 employees define possible every day using science, technology and engineering to create and deliver advanced systems, products and services.
